I’m sorry but I really don’t see it. I’ll ask other support team members to check the site on Firefox 26.0. Please edit the page then go to Gallery Options. Make sure that all the images on the list exist. If not, remove it. Remove browser cache then reload the page a few times. Test it on another browser. If you have a cache plugin, flush the settings.

Hi Devin,
wow, it’s great mystery…
I’m using Seven and yes, have quite a few add-ons installed.
I’ve tried to launch Firefox with deactivated-add-ons mode and everything works fine… It’s a mad stuff!!!
Thank you anyway for your kind help and support, you can close the thread.
